Through fully customized development, we not only ensure that new products achieve millimeter-level compatibility with your circuit boards but also enhance product assembly efficiency by over 30% through mold structure optimization, while reducing material wastage by 15%.

As a technical team with over 20 years of experience in precision mold manufacturing, we are equipped with state-of-the-art processing equipment, including CNC milling machines, cutting machines, EDM machines, planar grinders, CNC lathes, vertical drilling machines, and more.  

As the “precision engraver” of mold processing, CNC milling machines undertake the task of three-dimensional surface processing of key forming components such as mold cavities and cores. In automotive mold manufacturing, the machining accuracy of CNC milling machines directly determines product assembly clearances (such as the stability of connector insertion/removal force) and surface quality (such as the consistency of high-gloss textures on housings). The rigidity and dynamic response capabilities of their high-performance spindles are the core guarantees for achieving advanced processes like mirror-finish machining and micro-texture engraving.

Slow-speed wire cutting machines are core equipment in the mold processing industry for achieving high precision and complex shape cold processing, particularly for high-hardness mold materials such as quenched mold steel and hard alloys. From the large cutting edges of automotive body panel molds to the micro-cavities of electronic chip packaging molds, the machining precision and complex forming capabilities of these machines directly determine the “service life” and “product qualification rate” of the molds, making them indispensable core equipment in high-end mold manufacturing. 

Electrical discharge machining (EDM) machines are based on the principle of electrical discharge erosion. They remove material through high-frequency pulse discharges between the tool electrode and the workpiece without the need for physical cutting force. These machines are key equipment in mold processing for handling high-hardness materials, complex deep cavities, and irregular curved surfaces.
EDM machines directly determine the forming quality, service life, and manufacturing cost-effectiveness of molds, making them indispensable core equipment in the production of high-end molds, particularly precision plastic molds, die-casting molds, and tungsten carbide molds.

Surface grinders are not only used for new mold processing, but also play a role in mold “maintenance and repair” and “special requirement processing,” greatly improving the economic efficiency of molds.
From improving the surface quality of critical surfaces to repairing mold wear, their “high precision, high stability, and strong adaptability” directly determine the processing accuracy of subsequent processes and the final functional reliability of the mold. In precision mold processing, the processing quality of flat grinding machines can even affect the appearance and performance of the product, making them an “irreplaceable basic piece of equipment” in the mold manufacturing process.

CNC lathes operate on the principle of “digital program control of cutting tools along a rotational axis,” with core capabilities including high-precision rotational surface machining, automated forming of complex curved surfaces, and batch consistency control. They are the key equipment for addressing the machining requirements of rotational parts (such as mold cores, guide columns, and electrodes) in mold production. Whether it is plastic molds, stamping molds, or die-casting molds, the “circular cavities, cylindrical components, and ring-shaped structures” they contain all rely on CNC lathes for realization.
CNC lathes are the core equipment for processing rotary parts in mold production—from the forming of high-precision guide columns and mold cores, to the preparation of EDM rotary electrodes, to the consistency control of batch parts. Their characteristics of “high precision, high automation, and multi-process integration” directly determine the mold's “forming accuracy,” “assembly stability,” and “production efficiency.”

In mold production, vertical drilling machines are one of the core pieces of equipment for achieving high-precision hole machining, and are particularly suitable for machining various hole features in mold structures (such as locating holes, assembly holes, cooling holes, etc.). Due to the extremely high requirements for dimensional accuracy, positional accuracy, and surface quality in molds, vertical drilling machines, with their stable structure, controllable feed parameters, and flexible adaptability, have become an indispensable part of the mold manufacturing process.
The quality of their machining directly determines the assembly precision and final forming results of the mold, making them a crucial link in the transition from “part machining” to “finished product assembly” in mold manufacturing.
